Thanks for the addition to the group. Seriously considering building a drum roaster along the lines of oldgrumpus's. Love the design and craftsmanship.

AC Current handling question
Randy G
I am working on a semi-custom roaster build. I am running two heating element which will run concurrently. They measure at 18 ohms each. One 120 volts that would be 6.67 amps. Total heating power will be roughly 13.3 amps.

I need to trigger those with an SSR. I found one with the following ratings for the output capacity:
24-480 VAC volts
50/60 Hz
60 Amps

Would mean that at 120 volts (.25 of the output handling capacity for voltage) the output amperage handling capability would be 15 amps? Or not??

I could get two SSRs, one for each element, but am trying to keep things as simple as possible.

Nope, the max switchable current will be 60A at any voltage, a SSR is just a switch, nothing else, but not mechanical, no moveable parts, thus no wear.

Thank you for the reply. I did know thee were no "contacts" in there, but had no knowledge of the current-handling capability of how they work.

Unfortunately, just a few hours after I posted that the project went belly-up as the company wants the roaster back.
